Core Audio Format (.caf)

The CAF (Core Audio Format) file extension is a flexible, high-performance file format for storing audio data developed by Apple Inc. and introduced with Mac OS X 10.4 to the market. It supports a wide range of audio formats, enabling efficient audio recording, editing, and playback. CAF files are widely used in professional audio environments due to their support for 64-bit audio file offsets, allowing them to accommodate audio files of virtually unlimited size, making them ideal for long recordings and high-quality sound samples. They also support metadata, enabling the storage of additional information about the audio content.

Adaptive Multi-Rate Codec (.amr)

Adaptive Multi-Rate Codec (AMR) is a file extension used primarily in voice applications, including VoIP, audio messaging, and mobile phone telephony. Originating from the European Telecommunications Standards Institute (ETSI) in 1999, AMR files enable efficient compression and transmission of speech audio. The codec dynamically adjusts bit rates during transmission to optimize audio quality and network capacity. Its efficient bandwidth utilization and compatibility with various communication standards have made AMR a preferred choice for many modern communication systems.
